A Workhorse Yarn

The perfect work horse yarn and a YAK team favourite, Gilliatt is soft and bouncy woollen spun yarn made from 100% European merino wool and is a blend of white French merino and black Portuguese merino. 

This worsted weight yarn has a good stitch definition and a sticky handle which makes it suitable for all sorts of projects. Cables, stranded colourwork, lace, you name it – Gilliatt can do it all! 

Like all woollen spun yarn Gilliatt is lofty and warm. It blooms and softens after washing and wearing beautifully. A great choice for cosy winter jumpers, hats and scarves.

De Rerum Natura is a wonderful French brand specialising in European merino yarn. Sustainability and transparency are at the heart of De Rerum Natura’s ethos and this translates into every aspect of their business practice. 

50% of the merino wool comes from certified organic flocks raised by transhumance – an ancient practice in which flocks are moved from one grazing ground to another flowing a seasonal cycle. The rest of their fleece is sources from small traditional farms chosen for their respect for animal welfare. 

De Rerum Natura carries all manufacturing stages in a short circuit to insure traceability. For Gilliatt the fleeces are scoured in Belgium and Italy before being sent to France for spinning and dyeing.
